Our Thumb Screw Materials

Selecting the appropriate material for your thumb screws is crucial for ensuring optimal performance. Factors such as exposure to moisture, chemicals, or extreme temperatures, as well as the required load-bearing capacity should be considered when making your choice.

In Fivetech, the material options for our thumb screws include low carbon steel with zinc finish and passivated stainless steel: 

• Low Carbon Steel: Offers a good balance of strength and cost-effectiveness. It is also treated with a zinc finish for protection against rust and oxidation. However, its corrosion resistance is quite limited, thus it is mostly recommended as a captive panel screw for indoor applications where exposure to humidity and harsh weather conditions is lower.
• Stainless Steel: The preferred material for applications in harsh environments, both indoors and outdoors. It provides superior durability, as well as a corrosion resistance that is further enhanced by the chromium oxide layer from passivation.

Our Screw Knob Materials

At Fivetech, we provide captive screw knobs made out of aluminum and heat-resistant, fire-retardant ABS plastic. Other common options include steel, brass, nylon, resin, etc. The choice of knob material doesn’t just affect the aesthetic appeal of the thumb screw, but the durability and overall performance as well, which is why you should understand the difference between each option.

• Aluminum: This is a lightweight metal that offers a premium appearance, along with an excellent strength-to-weight ratio and corrosion resistance. It also provides high conductivity for heat and electricity, making it ideal for application in heat sinks or grounding components.
• ABS Plastic: This versatile material is lightweight, resistant to impact, and provides a comfortable grip for the knob. Our plastic knobs are also rated as heat resistant and fire retardant, which means they can insulate both heat and electricity to prevent potential hazards during applications in industrial equipment, automotive components, etc.
